Added a new optional argument to createMarker
ignoreAlphaLimits = false
This argument is only valid for checkpoint and arrow markers. It defines whether the alpha of these markers can be changed. If the argument is false, the marker has a constant alpha as before, i.e. checkpoint always 128 and arrow always 255. If the argument is true, alpha can be changed.
Default is false
I tested this using
createMarker
,setElementAlpha
,setMarkerColor
andsetMarkerType
on the server and client side. All my tests were successful
